STOVE.

SPECIFICATION forming part of Letters Patent No. 314,286, dated March 2-, 1885.

Application fifed February 23, 1884. (No mode'.)

To @ZZ whom it may concern.-

Be it known that I, JOHN B. Caoorrnn, re.-

siding in the city and county of St. Louis, in y the State of Missouri, have invented certain 5 new and useful Improvements in Stoves, as

set forth in the following specification.

The object of my invention is to provide means for introducing a current of external air into the oven during the process of cookio ing and for removing the impure gases and odors evolved in an oven during said process without unnecessary waste or shrinkage in the article being cooked, and retaining the nutritious elements inthe food being prepared, I5 and forcooking the same rapidly and thoroughly with a saving of fuel; and my invention consists in the means hereinafter set forth and claimed. v

I am aware that mechanismshave been here- 2o tofore patented and used for introducing external air into the oven and for distributing the same more or less throughout the oven, and communications have also been heretofore Iliade between the oven and the ascending flue. 2 5 The devices, howevelgheretofore patented and used for these purposes have been defective,` tirst, as to the introduction of the external air, in that either they have not supplied a sufficient quantity, or, on the contrary, by mal;- ing too large radial openings in the oven-door, they have supplied too great a quantity, and have been defective, secondly, in not properly and economically distributing the eXternal air at the proper points and in t-he proper manner in the oven; and, third, have further been defective, so far as they have taken the impure gases into the chimney-flue,in this, that they have been so arranged as that the soot from the flue would descend into the oven.

In the drawings, Figure l is a front elevation of a range or stove, with the door partially broken away and showing four of the air'dis tributing pipes. Fig. 2 is a perspective view ofa stove without its oven-door, showing the interior of the oven and the partition which separates the oven from the flue. Fig. 3 is a vertical section of the door, showing one method of applying said airdistributing pipes.

A represents the door of the oven, in which. preferably at the very center, C. are secured 5o the airdistributing pipes ci a a a in any convenient manner. Said pipes are open at both ends and take external air at the aperture C, and conduct the same to different parts of the oven, as desired, the inner ends ot some of said pipes being bent, as shown in Fig. 3.

In the partition which separates the oven from the chimney-flue at J J, Fig. 2, is shown a rotascope or register, w w, for the purpose hereinabove set forth.

Among the advantages arising from the use of said pipes, are that a uniform temperature may be maintained at all parts of the oven, and, further, that the external air is thereby heated to some extent before being introduced, at least to the extent of taking whateverchill there may be from the same.

I claiml. In an oven, air-distributing pipes forexternal air radiating from a central. point in 7o the oven-door, substantially as and for the purpose set forth.

2. The combination, in an oven, of radiating air-distributing pipes, substantially as described, with a rotascope or register in the partition separating the oven and the fiue, substantially as and for the purpose set forth.
